Warning by trying to edit picture

I was working on a project in corel draw and I was editing image by right click ->edit image in photopaint. After finishing in photopaint, I saved image and closed photopaint edit window. When I tried to edit next image I got warning. Picture of warning is attached. Now I can not edit images that way.

I allready try to restart coreldraw, but it doesn't do any good.

Has anyone had similar problem? Any ideas what could be wrong?
